RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 633,133, datedSeptember 19, 1899.

Application filed March 21, 1899. Serial No. 709,901. (No model.) I

T0 all whom it may concern:

Be itknown that I, ASA IV. GRIFFITH, acitizen of the United States ofAmerica, residing in Wilmington, in the county of New Castle, in theState of Delaware, have invented a certain new and useful Improvement inRail- Joints, of which the following is a true and exact description,reference being had to the accompanying drawings, which form apartthereof.

My invention relates to the construction of rail-joints, and has for itsobject to provide a firm and strong joint for securing together the endsof railway-rails.

The nature of my invention will be best understood as described inconnecti'on with the drawings in which it is illustrated, and in which-Figure 1 is a cross-section through the cen- A indicating the rail-Webspierced with holes a for the fish-plate bolts.

A2 indicates the rail-base, a2 a2 indicating the upper faces of thebase.

B B are ties.

O O are iish-plates, formed, as shown, with an upper flange O', piercedwith bolt-holes c', corresponding to the bolt-holes a' in the railweb,an intermediate iiange or center C?, adapted to fit on the upper facesCL2 of the railbase, and a lower flange C3, extending belo'w therail-base, provided with bolt-holes cB and with an inwardly-extendinglug C( at their lower edges. Preferably the iianges O3 are only formedin the center of the fish-plates C and of a length which will permitthem to extend between two adjacent ties B, over which will extend thelianges' O and center C2, as

, shown.

D is a U-shaped section of a length corresponding to that of the angesCB and formed so that when the face d of its central partabuts againstthe bottom of the rail-base its lateral arms D2 will extend down overthe lugs C4 of the flanges C3, against which the ends of said armsshould rest when the joint is fully erected. Preferably I form the faced' 0f section D with a slight convex curvature and form the section as awhole, so that its arms D2 will not actually Contact with lugs O4 untilthe flanges C3 of the {ish-plate and arms D2 of the section D are drawntogether by the bolts E', which are passed through oppositely-lyingholes d2 and c3 in arms D2 and anges C3 and made to draw the part-s intocontact by means of the nuts e.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- l. A rail-joint having in combination twofish-plates O O formed with iianges C3 extending below the rail-base andformed with inwardly-extending lugs C4 at their lower edge, a U -shapedsection D adapted to tit below the rail-base and having its arms D2extending over the lugs C4 of the fish-plates, bolts as E securing theupper .flanges of the fish-plates together and to the rail and twoseries of bolts E securing t-he flanges C3 ofthe fish-platesto theadjacent arms Dof the section D.

2. `A rail-joint Vhaving in combination two fish-plates C C formed withflanges C3 extend- 'ing below the rail-base and formed withinwardly-extending lugs O4 at their lower edge, a U-shaped section Dhaving a convexlycurved face d/ adapted to it below the rail'- baseandhavingits arms Dgext'ending overthe lugs O4 ofthe fish-plates, boltsas E securing the upper flanges of the fish-plates 'together and to therail and two series of bolts E securing the flanges C3 of thefish-plates to the 'adjacent arms D2 of thesection D.

A. IV. GRIFFITH.
